Can classic ASP and ASP.Net run in the same server

This explains about the co-existence of ASP and ASP.Net websites in the same server

Classic ASP and ASP.Net can co-exist in the same server and can run side by side without any problems. Infact, even different .Net framework versions can co-exist in the same server and all the sites can run.

Note: As a best practice, make sure to have a different application pool for each site so that it will be easier to recycle that particular site's pool only when anything goes wrong without disturbing other sites
